Earth’s Interior
A. Three main layers of the Earth
1.______________-outermost and thinnest layer
-Cool and solid rock.
-Divided into continental and oceanic crust.
2.____________-middle layer
-Hot and liquid rock, 80% of Earth’s volume
3. ____________-central layer of earth
-Divided into inner and outer core
-Outer= hot and liquid metal
-Inner= hot and solid metal
Continental Crust
-_______________ dense
-Thicker, deepest under mountains
Oceanic Crust
-Beneath the _______________
-__________ dense
-Thinner
B. Plate Tectonics
1. Alfred Wegner introduced the idea of __________, a large supercontinent.(He noticed the
coastlines fit together)
2. Broke apart because of ________________________, the theory that Earth’s surface is
made of large moving plates.
3. Movement happens because of Earth’s makeup
a. ________________- made of the “plates”; crust and upper mantle.
-Litho means_______________ and sphere means___________.
b. __________________- made of mantle below the lithosphere.
-Liquid and moves slowly.
-Astheno means_____________________.
C. Plate Boundaries
1. Any place plates meet and move is a ________________, a crack in the Earth.
-Three types of Plate Boundaries:
a. ________________ Boundary- move apart. (Diverge like divide)
b. ________________ Boundary-move together. (Converge like close together)
c. __________________________ Boundary-move along side
(Trans=across, like 2 trains moving in separate directions)
2. Divergent Boundary- causes ______________ and ridges (draw pictures below)
- Forms new _____________.
3. Convergent Boundary- causes __________, volcanoes, and ______________.
- Subduction occurs (one plate goes under the other plate)
(Draw pictures below)
4. Transform Fault Boundary- cause rocks to ___________ and break.
